4' Claims.

This invention relates generally to gasburning heating devices, particularly of the radiant ty-pe, and has special reference to the mounting of such devices and to the combination therewith of novel =means for collecting and carrying off gasesof combustion and, if desired, for reflectively controlling stray heat rays emanating from the burner element or elements of the device.

One object of the invention is to provide'a simple, inexpensive gas burning heating-device which ,maybe suspended from a ceiling, or otherwise -mounted above the area tobe heated, and which, .without the necessity of employing a fanorother air circulating means to direct the heated air downwardly, will operate efficiently .and effective ly to heat such area.

Another; object of theinvention is to provide, in. combination with a gas burner, or burners, -of the radiant type, which is or are supported above the area to be heated, novel hood means so associated with the burner or burners as to collect and-direct to a desired point gases emanating from the burner or burners.

.Another object of the invention is, optionally, to provide means for reflectively controlling stray -heat rays emanating from the burner or burners of the device so as to obtain maximum heating effect from the device within the area to be heated.

Another object of the invention is'to provide a heating device of the character mentioned which is cheap and easyto make and to install and which includes readily accessible valve means for regulating the flow of gas to the burner ele- -ment or elements thereof.

With the foregoing and other objects in View, which will become more fully apparent as the nature of the invention is better understood, the same consists in the novel combination and ar- "rangement of features as will be hereinafter more fully described, illustrated in the accompanying drawings and defined in the appended claims.

In the drawings, wherein like characters of reference denote corresponding parts in the different views:-

' Figure 1 is a central, vertical, longitudinal sec- .tion through a gas burning heating device constructed in accordance with one practical embodiment of the invention. I

.Figure '2 is a transverse section on the line 2-2 of Fi 1. V

Figure 3.is aview similar to Fig.1 illustrating an alternative embodiment of the invention; and F-igurel is a view similar to Figs. 1 and 3-illusvice.

tratinganother alternative embodiment of the invention.

Referring to the drawings in detail, first to the embodiment of the :invention illustrated in Figs. 1 and 2, A designates, generally, a hood 5 which may be formed from sheet metal or other suitable material and which may, if desired, be

lined, either entirely or in part, with heat insulating or heat ray reflecting material, or with a combination of such materials. This hood may 10 be of any suitable size and shape, depending upon the number, the size, and the relative arrange ment of the burner elements embodied in the de- :In the present instance, according to the particular embodiment of the invention illustratl5 eol iii-Figs. 1 and 2, the 'device comprises two -burner elements disposed, generally speaking, in :back toiback relationship. 'The hood A, in longitudinal section, therefore may be appropriately inthe form of atrapezoid having its shorter and 2 longerbases at'itstop and bottom, respectively,

as shown. In detail, said hood A comprises, in the case of the first embodiment of the invention, "apair of vertically disposed side walls l9, to, a

top wall I l, and a pair of end walls l2, l2 extend- 25 ing downwardly and outwardly at suitable inclinations-from the ends of said top wall. At its bottom said hood is open, while in its top wall ll is'a gas escape opening l3, or, if desired, a plural- -.ity of gas escape openings, with which maybe 30 connected a conduit orconduitsleading to any suitablepoint of gas discharge.

The hood A is designed to be suspended, either from a ceiling or from any other suitable support, above an area tobe heated, and may be suspended in any suitable manner. In the present instance a'gas supply pipe l4. extends down- "wardly through the top wall ll of said hood, ap-

proximately midway between the ends and adjacent to one side thereof, and is suitably fastened 40 "the hood obviously may be firmly suspended from a ceiling or from any other desired support. 9

Within the hood A is mounted a pair of .burner elements l1, l1, preferably of the radiant type, which may be of any known or desired construction. These burner elements are disposed, respectively, on opposite sides of the medial, transverse plane of the hood and extend transversely of said hood at suitableupward and outward inclinations; for example, at angles of approxi- 1 a a the hood. If provided, this shield element 26 7 mately fortyefive degrees to the horizontal. They {may be mounted within the hood in any .desired manner; for example, between upper and lower supporting pieces 18 and 19, respectively, which extend between the side walls of the hood. In' this connection, if the2burner elements aret mounted by means of upper and lower cross pieces as shown, the. upper cross pieces are suitably spacedfromthe top and the end walls of.

the hood for the passage of fumes and gases from V in front of the burners into the space within the [hood behind the burners for escape through the opening or openings' l3. 1 g

a At the lower end of' the gas supply pipe His a valve 26 with which is connected one of the burner elements ll, said valve being operable by V means of a depending handle 2| to regulate the flow of gas to the'bu'rner element IT with which it is connected independently of the flow' of gas 'to theother burner element. From the pipe I4 at a point above the valve 20 agbrancha pipe 22 leads to the second burner element, this branch pipe including a valve 23 having a depending hood space behind said insulating 1 elements.

' handle! by which it maybe controlled to regulatethe gas supply to the second burner element independentlyof the gas supply to the first men- I .tionedburner element. i V 7 'Preferably,;but not necessarily, aheat insulating element 25 is mounted behind'each burner element both to assist in the radiation of heat downwardly and outwardly fromthe burner elements'and to prevent heat'losses through the Preferably, too, but not necessarily, the space between the bottoms of theburner elements is closed by ashield element 26 of sheet metal or 7 other suitable material to prevent heated air below the hood from circulating upwardly directly through the middle portion of the hood to the gas escape opening or openings 13 in'the topof hasair supply ports or holes 2 b and also serves to conceal from view. the pipe connections, valves and burner element mounting means and thereby adds to the attractiveness of thedevice; 'It has been found that the burner elements I],

H operate very satisfactorilywhen disposed at l inclinations as shown, and that theyserveeffectivelylto radiate heat downwardly and outwardly to heat'an area above which the heating device is mounted. Moreover it hasbeen found fthatby having. the end walls |'2,;l2 disposed at downward and outward inclinations in front of the burner elements l1,,l1, respectively, all heat "waves emanating laterally outward from' the burner elements are intercepted and directed downwardly, thereby contributing to the efliciency of the devicein heating an area there- 1 In some instances, due to lack of installation space or because it is desired'that some heat shall be radiated .laterallyi outward from the device, .or for other reasons, it may be desirable to construct the device without having the hood "A include end walls extending downwardly and 7 outwardly in front of the burner elements. Fig.

3' of the drawings illustrates aiconstruction of this type, said construction being substantially the sameas the Figs. 1 and2'constructionand amounting, in efiect,,simply to the'elimination of the hood end walls J2, [2 of the Figsl and 2 construction and having the hood openfat its ends in front of, the burner elements. a

If desired, the. device may comprise more than. two burner elements. In thatevent, the

' back of the burner element by an end wall desig ward and outwardinclination to the horizontal,

means closing the space between the inner spacedthe end walls of the hood extending from above T burner elements preferably are spaced equal an- 'gular distances apart as viewed in plan-and the shape of thehood'A in horizontal section is correspondingly varied. For' example, 'if three burner elements "are used the hood may be of" 5 triangular shape, or if four burner'elements are used'the hood may be of rectangular shape, or if six burner elements are usedthe hood may be of hexagonal shape.- On the other hand, the device obviously may include only a singleburner element. .In that case its construction 'may be' as illustrated in Fig. 4, amounting, inreffect, to elimination of one-half of the device as shown in Figs. 1 and 2 and closingjof the hood at the nated as 21. In this connection, the" construc- 1tion illustrated in'Fig. 4 mayalso be varied by eliminating thedownwardly and outwardly -inclined hood end wall llffrom iniront of the burner'element as suggested by the Fig. 3.00m 20 a struction. I i r v V V a Without further description a is thought'that the features and advantages .of' the invention, will be. readily apparent to those skilled in the "art, and it will of course be understood that as changes in the form, proportionand minor details of construction may :be resorted to, without departing from the spirit; of the invention and scope'of, the appended claims.
